HENRY KROENKE ERNSTBINDEVVALD, YOF NEW YORK, N. Y.

REFmeER-ATOR.

SPECIFICATION forming part of Letters Patent No. 508,520, datedNovember 14, 1893.y Application filed July 27, '1893. Serial No. 481,597. (No model l To all whom t may concern.'

Be it known that we, HENRY KROENKE and ERNST BINDEWALD, citizens of the -United States, residing in the city of New York, in the county and State of New York, have invented certain new and useful Improvements 1n Refrigerators, ,of which the following is a specification.

Our inventionv Vrelates to certain improvements in refrigerators of that class which are used by grocers, butter merchants and others, for cooling and preserving of butter, milk and similar articles, the invention relating more especlally to that class of Y refrigerators in which a swing-door is arranged in the frontwall of the refrigerator, and adapted to be opened and pushed inwardly so as to give access to the main storage chamber while the coldair is prevented from escaping to the outside of the refrigerator and compelled to pass into another chamber of the refrigerator.

The invention consists of a refrigerator in which the door leading to the main storage chamber is adapted to be lifted and pushed back in suitable ways into a horizontal position,so that it abuts with its rear-.partagainst a trough for the drip-water from the ice-charnber, whereby the supply of cold air to the storage-chamber is intercepted and conducted to the lower storage-chamber of the refrigerator. The door of the storage-chamber is provided with fixed pivot-pins at its corners by which it is guided in grooved ways of the side-walls of the storage-chamber and swung along recessed and rounded off corner-pieces of said side walls into vertical position, so as to close the front of the storage-chamber, the upper beveled edge of the swing-door fitting along the corresponding beveled edge of the front wall of the refrigerator when the door is in closed position, and along the inclined wall of the drip-trough when the door is in open position.

In the accompanying .'drawings, Figure l represents a front-elevation of our improved refrigerator.- Fig. 2 is a vertical transverse section of the same on line 2, 2, Fig. l. Figs. 3 and lare vertical transverse sections, drawn on a larger scale, and showing the door of the storage-chamber in partly and entirely Fig. 5'is a detail rear elevation of the door of the storage-chamber, and

Fig. 6 is-a detail perspective view of one of the pivots and corner pieces, on which the door swings into open or closed position.

Similar letters of reference indicate corresponding parts.

Referringto the drawings, A represents a refrigeratorin which the ice-chamber B is arranged atthetop part of the same above the main storage chamber B. The drip from the ice-chamberv B is conducted into a transverse trough C that is arranged below a discharge opening b in the inclined bottom of the icechamber, saidgtro'ugh, being arranged at a sufficient distance from the rear wall of the refrigerator to permit the arrangement of a channel or duct b by which ,thev cold air is conducted into the lower 'storage-chamber B2 of the refrigerator in which the milk-cans or other articles are stored. A partition b2 separates the/main storage-chamber B and the trough O from the rear-wall of the refrigerator and forms the channel b behind said in front of the trough C is preferably used;

for the storage of butter in tubs or for similar articles. The door D of the storagechamber B is provided near its upperA corners with fixed pivots d that rest in the recessed cast-metal corner-pieces d attached to rthe 'sidel walls of the main Vstorage chamber B. The pivots d `are so constructed that they engage the recessed' corner-pieces d when the door D is in closed position and vertically in line with the front wall of the refrigerator, as shown in Fig. 2. The upper edge e of the door D is beveled so as to correspond with'the inclination of the front wall of the trough C, the meeting edge e in the front wall ofthe refrigerator being provided with a similar bevel so that a tight fit between the door D and front wall of the refrigerator is obtained when the door is placed in closed position. The recessed cornertion.

IOO

d extend along the side walls of the main storage chamber B', grooved waysd2 in which the pivots d are guided when the door D is swung into horizontal or nearly horizontal position, as shown clearly in Figs. 3 and 4, the door being pushed inward until its beveled upper edge e abuts against the inclined front Wall of the trough C, as shown in Fig. 4. When the door D is placed in this position, the main storage chamber B' is open, so that access is given to the same, while the supply of cold air to the storage chamber is intercepted and the air compelled to pass from along the rear channel b into the lower storage chamber of the refrigerator, as indicated by arrows in Fig. 4. The pivots d are provided with curved shanks als of rectangular cross-section, which are attached by recessed straps d4l and intermediate blocks d5 to the rear of the door D as shown clearly in Figs. 5 and 6. The inner ends of the shanks d3 and the ends of the straps d4 are attached by screws d6 to the blocks d5 and the frame of the door. The fastening of the pivots d by the straps d4 and intermediate blocks d5 imparts considerable strength to the pivots and brings the same in line with the grooved ways d2 and the recesses of the corner pieces d', so that the moving of the door D from its closed into partlyr and entirely open position in the refrigerator, or vice versa, from closed into open position, can be accomplished with great facility.

Having thus described our invention, we claim as new and desire to secure by Letters Patent- 1. The combination, with the main-storage chamber of a refrigerator, of an ice-chamber, a lower storage-chamber, a trough extending transversely across the upper part of the main storage-chamber, a partition in the rear-part of the main storage-chamber, said partition forming a channel or duct between the main storage-chamber and its trough and the rearwall of the refrigerator, guide-ways extending from the trough to the front wall of the refrigerator, recessed corner-pieces at the front ends of said guide-ways, and a door provided with pivots and adapted to be moved from its closed position into horizontal position in the interior of the refrigerator and backagain into closed position, substantially as set forth.

2. The combination, with the main storagechamber of a refrigerator, of an ice-chamber, a lower storage-charnber, a trough extending transversely across the upper part of the main storage-chamber, a partition at the rear part of the main storagechamber, said partition forming a channel or duet between the main storage-chamber and its trough -and the rearwall of the refrigerator, guide-ways extending from the trough to the front wail of the refrigerator, recessed corner-pieces having rounded off corners, located at the front-ends of the guide-ways, and a door provided with pivots and adaptedv to be moved fromits closed position into horizontal position in the interior of the refrigerator and back again i'nto closed position, said doors and the front-walll of the refrigerator being provided with beveled meeting-edges corresponding to the inclination of the front-wall of the trough, substantially as set forth.

3. The combination, with the storage-chamber of a refrigerator, a swing-door in the front wall of the same, pivots having rectangular Shanks attached to the upper part of the swingdoor, recessed straps extending over said shanks,blocks interposed between the Shanks and straps and thev door, recessed cornerpieces having rounded oi outer corners, a transverse trough in the upper part of the storage-chamber, and grooved ways extending from the recesseslof the corner-pieces to the front wall of thetrough, substantially as set forth.

4. In a refrigerator, a swing-door provided with pivots, recessed straps extending over the Shanks of the pivots, blocks interposed between the straps and doorframe,and screws for attaching the Shanks, straps, and blocks to the door-frame, substantially as set forth.

In testimony that we claim the foregoing as our invention we have signed our names in presence of two subscribing witnesses.
